To all whom it may concern.

Be it known that I PETER Wnnnv, a citizen of the United States,residing at Newcastle, in the county of Henry and State of Indiana, have invented a new and useful Paperinding Mechanism for Musical Instruments, of which the following is a specification. T p

t This invention relates to that class of musical instruments which are controlled by strips of perforated paper.

The especial object ofthis invention is to provide simple, efficient and noiseless means for connecting a motor to the winding rolls in such a Way that the entire motor is movably mounted so that the same can be shifted to change the connections from the motor for winding or rewinding'the paper over the tracker-board.

Further objects of this invention are to provide a simple form of hand-lever for board during re-windingy tipping the motor; to provide for tightening the winding chain during re-winding;

and to provide for releasing the frictionbrake which tensions the music-sheet while being drawn forward over the tracker- To these ends, this inventionconsists instruments, 'and of the combinations of parts therefor as hereinafter described and more particularly pointed. out. in the claims at the endof this specification.

In the accompanying drawing, Figure 1 is a front View of suf'ficicnt'parts of a paperwinding mechanism to illustrate the application of this invention thereto. Fig. 2 is a detail view of there-winding lever and connections controlled therefrom. Fig. 3 is a detail view of the winding gears, and Fig. 4 is a detail view of the frictionbrake which tensions the i'imsic-sheet and the releasingtinger therefor.

In that class of musical instruments to which this invention relates a number of different constructions have been employed for providing shiftable connections between a motor and the w'indlng-rolls. In constructions which are most generally employed the motor (which may be either theordinary wind-motor, spring-motor, or other source of power) is mounted in fixed position, and various shifting devices have been employed of the paper-winding mechanism for musical for coupling the :motor to either wind the music-sheet over the tracker-board, or to rewind the same when-a musical composition is finished. I have found in practice that it. is possible to provide a construction in which the entire motor is mounted on a movable support so that the motor can be bodily moved or shifted to provide the d e sired change of connection, and that this can be-done in a construction which is less rattly, and which is less liable to derangement. than the connections from a stationarily placedmotor which has heretofore ordinarily been employed.-

l-teferring to the accompanying drawing for a detail description of an ap niratus em.- botlying this invention, as shown in Fig. 1, It designates the inusic-s nioh From the music-spool It the music-sheet S is drawn over the tracker-board W. These parts are of the "ordinary or well known construction.

At one side of the winding rolls and the tracl'cer-board is a pivoted support 500 which carries the motor. As herein illustrated, the motor may be of the ordinary type of windmotor, in the present instance. con'iprising the three sliding valves V which control three operating pncumatics for turning the motor crank-shaft C. from the wind-motor in the ordinary manner through a pipe P. In Fig. 1. of the drawings. 1 have shown the valves V mounted in slide-ways and held in place by the ordii'iary small wooden clips. The crankshaft C of the motor is provided at its end with a small pinion which normally meshes with a. ear (30 on the end of the shaft of the winding roll W." Also mounted on the'crank-shaft C is a sproekctavheel which is connected by a SPJTOClflE'i'Ullflll] 54 to a sprocket-wheel mounted on a normally disconnected sliding clutcl'i 61. Engaging the chain 54 is a tigl'itening-wheel carried The air is exhausted by the spring-arm When the parts are in normal position the chain 54 runs comparatively loosely.

On the shaft of the friction'disk 57 which is normally engaged by a tension brake 58, shown. in Fig; 4, and cooperating with the tension-brake '58 is a releasing arm 59. The normally disconnected sliding clutch ,6] is controlled by a lever 55 which is connected by a link 66 to the motor casing. 4

Considering now the means for tipping or tilting the motor, and the operation which results theret'rom, as shown in Fig. 2,18 designates a shitting lever which is connected by a link (35 to an arm 6% extending from a vertical rock-shaft 52. Bear itsupper end the rock-shaft is provided with an arm (32 which engages and cooperates with a cam or incline es of the motor support 500. The motor may be held in its normal or horizontal position by a spring (57. ll means ot this construction when the motor is tipped or tilted by the connections from the lever lo, the driving pinion 53 will be moved down out of mesh with the gear tith-as shown by dotted llll0S lI1' 111g. 3, and

Fat the same time, the sliding clutch til will be' thfrown into mesh so that the 1nusic-sheet will, be rewound upon the music-spool it.

' At the same time, the tipping oi the motor lowers the tightening roii if) so that the same bears more strongly upon the s 'irochebchain 54c and tends to tension or tightenthe same while, at the same time, the releasing arin 5t) tends to IHQYGthB friction-brake :38 out of engagement with its disk- 57 That is to say, in a complete paper-winding mechanism for a musical instrument constructed according to this invention, the change of "connections for winding or rewinding the music-sheet is secured by a bodily movement, preferably a tipping ortilting ot the motor; and, at the same time, the tension ot the drive-chain which is normally loose dur;

ing the wiiidiiig'of the music is increased [during the rewind-mg operation, and the friction-brake which tensions the music during winding is released during the rewindiiig.

' l am aware that changes may be made in. lhe con truction of my paper-\\'i-nding mechanism for musical instruments to adapt the same to various places and locations without lepartiiig from-the scope of my invention as expressed in the claims. 1 do not .wish, therefore, t0 be limited to the paper mounted motor, and means for tipping or instruments, the combination ofclutch into operation rewound.
